A high current pulse activator for the prolongation of Lead-acid batteries

We report here that a newly invented pulse activator make it possible to reduce sulphation on the electrode of lead-acid battery resulting the prolongation of the battery life. A high-pulsed current is discharged and then a high pulsed current charging is made. The high current used is 5 to 10 C. Through the battery evaluation test of charging and discharging, the effectiveness of the performance of this high current pulse activator is proved.

ITE's Polymer Activator Effect on Lead-acid Batteries

The ITE organic polymer activators for extending the life of lead-acid batteries were first developed by a Japanese group in 1997 led by Dr. Akiya Kozawa. The initial activator was a composite mixture of carbon and polyvinyl alcohol. A US Patent (5,958,623) was issued on September 28, 1999 for this new lead-acid battery activator. Later research found that the organic polymer alone was very effective which started a wide search for other such organic additives. The most effective one to date is an acrylic polymer with a high molecular weight. This paper summarizes the current results involving this acrylic polymer.
